Achievements not posting

When do they usual post to the achievements section? I completed all three rings for the first time today and so far there is nothing showing at just before midnight.

Edit: They posted to the section at midnight.

I get the achievement reminders when the rings close but as said, my watch started having a few incidents like family members where logged workouts did not close the rings.

I'm not sure how long you've had the watch but you might need to revisit your goals. This is funny in our family because we have parents constantly crushing the teenager who's got a watch. The nudge factor is not working with him like it is with his folks.
